</ul>
<h2><a class="anchor" id="autotoc_md10"></a>
0.9.0 December 26 2019</h2>
<ul>
<li><p class="startli">Fix to avoid duplicate images being copied to an libxlsxwriter file. Excel uses an optimization where it only stores one copy of a repeated/duplicate image in a workbook. Libxlsxwriter didn't do this which meant that the file size would increase when then was a large number of repeated images. This release fixes that issue and replicates Excel's behavior.</p>
<p class="startli">Note, that this change adds a dependency on the <a href="https://openwall.info/wiki/people/solar/software/public-domain-source-code/md5">Openwall MD5</a> library, which is now included with the libxlsxwriter third party source files. It is possible to compile libxlsxwriter without this library, and thus getting the older behavior, by passing <code>USE_NO_MD5=1</code> to make.</p>
</li>
</ul>
<h2><a class="anchor" id="autotoc_md11"></a>
0.8.9 December 16 2019</h2>

<li>Fixed several <code><a class="el" href="worksheet_8h.html#a9b2ac96ee23574a432f5703eedcaf9a1">worksheet_write_url()</a></code> edge cases.</li>
</ul>
<h2><a class="anchor" id="autotoc_md12"></a>
0.8.8 November 17 2019</h2>
<ul>
<li>Added option to allow a user defined, or overridden, image description used with <code><a class="el" href="worksheet_8h.html#a4529d77bcefcf478b8209f46fe730f6f" title="Insert an image in a worksheet cell.">worksheet_insert_image()</a></code>. By default it uses the filename as the description. Issue <a href="https://github.com/jmcnamara/libxlsxwriter/issues/238">#238</a>.</li>
<li>Added Windows portable version of <code>fopen</code> to handle utf8 filenames when working with images. Issue <a href="https://github.com/jmcnamara/libxlsxwriter/issues/238">#238</a>.</li>
<li>Added an option to allow chart fonts to be rotation to 270 deg to give a stacked orientation. Also added support for East Asian vertical chart fonts.</li>
<li>Refactored struct types used in pubic APIs to remove or document hidden fields. <b>Note:</b> This change introduces backward incompatible API changes. However, it should minimize any future changes of this nature. See issue <a href="https://github.com/jmcnamara/libxlsxwriter/issues/252">#252</a>.</li>
</ul>
<h2><a class="anchor" id="autotoc_md13"></a>
0.8.7 June 20 2019</h2>
<ul>
<li>Added support for adding VBA macros to workbooks. These macros can be extracted from existing xlsm files, created in Excel, and added to new xlsm files.

<li>Added support for ZIP64 extensions when writing very large xlsx files to allow the zip container, or individual XML files within it, to be greater than 4 GB.
